What are the structures of photovoltaic tiles?

Sep. 29, 2024

Photovoltaic tiles are a new type of BIPV photovoltaic building integrated material. Its structure has the characteristics of both building materials and photovoltaic materials. It is mainly composed of double-layer laminated tempered glass and photovoltaic modules, as follows: tempered glass-poe film-Miasole chip-poe film-tempered glass. Miasole flexible copper indium gallium selenide chip is a high-efficiency flexible component.


Tempered glass: Tempered glass is actually a prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc.


Poe film: Poe film has excellent characteristics such as high water vapor barrier rate, high visible light transmittance, high volume, resistivity, excellent weather resistance and long-term anti-PID performance, which can better improve the long-term reliability of the module.


Miasole chip: Currently, the flexible sputtering CIGS thin-film solar technology with the highest conversion efficiency in the world, its cells are flexible and lightweight, and can provide efficient solutions for application scenarios such as power generation and green building, mobile energy, etc.

Such a structure not only ensures the beauty of the product, but also ensures the stability of the product and avoids the hidden cracks of crystalline silicon components.

Will the shadow of houses, leaves or even bird droppings on photovoltaic modules affect the power generation system?

Shadows on the components of the photovoltaic power generation system and obstructions caused by bird droppings will have a relatively large impact on the power generation system. The electrical characteristics of the solar cells used in each component are basically the same. Otherwise, the so-called hot spot effect will occur on the cells with poor electrical performance or being obscured. The obscured solar cell components in a series connection will be treated as loads to consume the energy generated by other illuminated solar cell components. The obscured solar cell components will generate heat at this time. This is the thermal effect phenomenon.

Is it necessary to disconnect the photovoltaic power generation system during thunderstorms?

There will be professional installers to carry out lightning protection measures for the photovoltaic power station, such as grounding wires, professional lightning protection blocks for junction boxes, etc. Don't worry, when installing the photovoltaic power station, you need to take lightning protection measures for the photovoltaic power station, such as grounding and safe arrangement of cables.

How often do components need to be cleaned? What should be paid attention to during cleaning?

According to the product supplier's instructions, maintain the parts that need to be checked regularly. The main maintenance work of the system is to wipe the components. In areas with heavy rain, manual wiping is generally not required, and cleaning is done about once a month in the non-rainy season. The number of wiping can be increased as appropriate in areas with heavy dustfall. Areas with heavy snowfall should clear heavy snow in time to avoid affecting power generation and uneven occlusion caused by snowmelt, and the number of shielding components or debris should be cleaned in time.

What occasions are distributed solar power generation systems suitable for?

Distributed photovoltaic power generation refers specifically to photovoltaic power generation facilities that are built near user sites, with the operating mode of self-generation and self-use on the user side, excess electricity connected to the grid, and balanced regulation in the distribution system. Distributed photovoltaic power generation uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use.
